CROSSING GRATE FOR GU'ITERS.

' Application filed June 26, 1925.

To all whom it may concern Be it known that I, LEON SMITH, a citizen ofthe United States, residing at Hammondsport, in the county of Steubenand State of New York, have invented certain new and useful Improvementsin a Cross ing Grate for Gutters, of which the following is aspecification.

This invention relates to an improved grate or open-work metalstructure, adapted for disposition over a gutter extending crosswise ofa highway, the object being to provide a means for draining surfacewater into the gutter and to permit convenient passage of vehiclesthereover.

Briefly, the invent-ion consists in the digging of a gutter transverselyof a road bed, placing a concrete trough in 'this gutter, and fashioningthe trough to receive a removable grate or grid disposed flush with thesurface of the road.

The features and advantages derived from the particular construction andarrangement of parts serving to produce the novelty alleged in theappended claim, will become apparent from the following detaileddescription.

In the accompanying drawing forming a part of this. application and inwhich like numerals are employed to designate like parts throughout thesame:

Figure 1 is a top plan view of a portion of a road-bed showing theimproved device in place thereon.

Figure 2 is a view like Figure 1 showing a slightly difierent embodimentof the invention.

Figure 8 is a detail sectional view showing the manner of supporting andanchoring the grate.

As before intimated, in carrying out the invention, I dig a guttercrosswise of the road, this gutter being of any appropriate depth tocarry off storm water with considerable rapidity. A suitable form isplaced in the gutter and liquid concrete is poured into this form andallowed to set to form what may be referred to as a concrete trough,-

the bottom of which is represented by the reference character 1, and theside walls by the reference characters 2. If desired, the ends of theside walls may flare outwardly to eifectively conduct the flowing waterinto Serial No. 39,783.

the usual longitudinal gutter alongside of the read. From Figure 3 itwill be seen that in making the concrete trough, a ledge is provided atthe upper portions of the side walls to serve as a rest for the improvedgrate. Moreover, a plurality of bolts 3 are embedded in the concrete,the threaded ends extending above the surface of the ledge as shown. Thegrate is represented generally by the reference character 4:. The gridcomprises longitudinally extending transversely spaced stringers 5having holes at their opposite ends fitted over and connected with thethreaded upper ends of the aforesaid bolts 3. Retaining nuts areprovided for this purpose as shown in Figure 3. Riveted or otherwisesecurely fastened to these stringers are bars 6 arranged at ratherclosely spaced intervals. To secure rigidity of construction, tie rods 7are passed through these bars, as shown. Retaining nuts are placed onthe opposite sides of each bar as plainly indicated in Figure 1. Thus, areadily removable grate is provided wherein the upper surfaces of thebars are disposed substantially flush with the surface of the road,whereby to provide a smooth bridge for the gutter, and an efficientmeans for carrying off the water by draining it into the gutter beneaththe grate. The only distinction between the showing of the iu vention inFigures 1 and 2, is that the gut ter and grate are of straight design,whereas in Figure 2 the bars of the grate are constructed to disposethem substantially diagonal to the path of travel. This facilitatesmovement of the vehicles over the bars to some extent.

A careful consideration of the description in connection with thedrawings will enable persons skilled in the art to which the inventionrelates to obtain a. clear understand ing of the same. Therefore, a morelengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown anddescribed, it is to be understood that minor changes coming within thefield of invention claimed may be resorted to if desired.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is In a structure of the class described, a

extending through said holes to anchor said stringers in place, and aplurality of longitudinally spaced cross bars fastened to said 1stringers, together With tie rods connecting said bars together.

In testimony whereof I aifix my signature.

LEON SMITH.
